Abstract: A system for forming and releasing an aqueous peracid solution is disclosed. The system includes a container and a peracid forming composition provided within the container. The container is permeable to the passage of water and aqueous peracid solution. The peracid forming composition includes a peracid precursor and a peroxygen source. Preferably, the peracid forming composition includes a chemical heater capable of releasing heat upon hydration. When placed in water, water enters the container and interacts with the peracid forming composition provided within the container. The water combines with the peracid precursor and peroxygen source to provide an aqueous peracid composition. The presence of a chemical heater within the container provides for the generation of heat within the container which enhances the rate of peracid formation. The peracid solution leaves the container and forms an effective sanitizing amount of sanitizer. A composition for forming and releasing an aqueous peracid solution is disclosed. The composition can include a mixture of peracid forming components or a composite structure containing peracid forming components adhered together. Methods of sanitizing a surface having a population of microorganisms are provided, and methods for manufacturing are provided.
